Regarding the reflash of the Calibers software that's can be determined
by its build date as shown on the sticker on drivers door,if it shows before
June 06 then it's probably a candidate for the reflash.
Another way is goto Dodge.com and check your VIN# against the recall
listings,numerous Caliber owners of those built previous to June 06
have had theirs reflashed with varying results.
